The general policy is: core conformance to standards in Saxon-HE, optional
features and extensibility features in Saxon-PE, performance optimizations and
advanced features (streaming, schema-awareness) in Saxon-EE. There are
variations within that, of course.

The vast majority of the EXSLT functions, for example the date-and-time
function, have really been obsolete since 2.0 came out, and could easily be
coded as pure XSLT 2.0 functions if you really want them.
